Title: Heat exchanger of type of integrated cores of different kinds
Inventor: SUGIMOTO TATSUO
IPC: F28F9/26
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To suppress lowering of a heat exchange efficiency of a condenser core part in a heat exchanger wherein the condenser core part and a radiator core part are integrated. SOLUTION: In a side plate 4 coupling two core parts 2 and 3, notch parts 41a are formed in the end parts on the sides of radiator core tanks 5 and 6. Since a route of heat conduction in a portion wherein the amount of heat conduction is the largest is cut off thereby, the heat conduction can be interrupted effectively. Accordingly, lowering of a heat exchange efficiency in the condenser core part 2 can be suppressed. Moreover, a plurality of cut parts 41 are formed in portions corresponding to a gap between the two core parts 2 and 3 and, therefore, a jig for positioning tubes 21 and 31 of the two core parts and cooling fins 22 and 32 thereof can be fitted to the cut parts 41 at the time when cores are assembled. Accordingly, the fitting properties of the tubes 21 and 32 and the cooling fins 22 and 32 are improved.

Title: Vapor phase epitaxy method for organic metal
Inventor: NARIZUKA SHIGEYA
IPC: H01L21/205
Filed: 1990-01-31
Abstract: PURPOSE:To obtain a highly controllable method of vapor phase epitaxy of organic metal which permits control of composition as desired while lattice matching with a substrate is maintained by selectively mixing a plurality of materials to be subjected to lattice matching with a semiconductor substrate and growing semiconductor crystals by means of using a third mixture wherein a first and a second mixtures are mixed at a predetermined mixing rate. CONSTITUTION:When InGaAlP is to be epitaxially grown while it is subjected to lattice matching with a GaAs substrate, a set is made of TMI11 and TMG12 bubblers which are organic metal materials and another set is made of TMI13 and TMA14 bubblers. Under flow rate conditions which allow lattice matching with the GaAs substrate, each bubbler is bubbled by hydrogen whose flow rate is controlled by using a flow rate controller 15. Then organic metal gasses from the respective bubblers are mixed in respective mixing units 16a, 16b. Respective organic metal mixture gases mixed in the mixing units 16a, 16b are in a mixture ratio which allows lattice matching with the GaAs substrate. Then the flow rates of the gases are controlled by flow rate controllers 17a, 17b, mixed in a second mixing unit 18 and used for crystal growth together with PH3 which has been led through a reactive tube 19 kept at a reduced pressure and supplied from a cylinder. Thus control of lattice matching and control of composition are independently performed.

IPC: G03F1/84
Filed: 1984-02-10
Abstract: PURPOSE:To suppress or prevent attaching of foreign matter onto a test piece to improve reliability of inspection and to prevent a defect from occurring at the next process, by providing with a stage supporting the test piece with its surface oriented vertically, and by setting an optical system opposing the stage so that at least the optical axis of the object side is horizontal. CONSTITUTION:A wafer W which has been carried by an automatic handling means 17 is vacuum-attracted and supported vertically on the surface of the movable table 9. The wafer W is focused against the microscope 7 by moving the wafer W in the Z direction with the stage 5, and an operator can observe and inspect the entire surface of the wafer W with the microscope 7 by moving it so as to scan in both the X and Y directions. At the same time, the wafer surface is pictured by the ITV camera 16 and automatically inspected. Since the wafer W is always kept vertically during the inspection, foreign matter such as dust existing in the atmosphere hardly rides on the surface of the wafer W and hardly sticks to it, if the foreign matter falls.

IPC: B22D11/12
Filed: 1986-02-05
Abstract: PURPOSE:To break dendrite arm, to obtain equi-axed crystal for solidified structure and to prevent segregation by discharging electric capacitor for a short time and shifting non-solidifying liquid phase in casting slab by Lorentz force generated under interaction between a static magnetic field pre-supplied. CONSTITUTION:Under supplying the static magnetic field in the casting slab 4, in which the inner part is non-solidifying state, by a magnetic field generator 2, an electric charge of the capacitor 6 is discharged by using electrode rolls 5a, 5b for a short time, as pulsation in the casting slab. Lorentz force is obtd. by relative action between the discharge and the magnetic field, and molten metal, which is non-solidifying part in the casting slab 4, is shifted under large flow speed only by a little length. In this way, this force breaks the dendrite structure under growing and the broken dendrite structure causes generation of equi-axed crystal as the nucleus in the solidified part. Therefore, interruption of the casting operation and generation of inverse segregation is prevented.

Abstract: PURPOSE:To maintain a picture at a fixed degrees of fixing and gloss by providing a heating temperature changing means changing a heating temperature, which set by a heating temperature setting means, according to a carrying speed changed by a carrying speed changing means. CONSTITUTION:A copying machine main device is provided with a light amount sensor 41 detecting an exposure amount.

The heating temperature is set by operating a gloss selecting switch 54 and a magnification selecting switch 55, and is compared with its upper limit. When the detected exposure amount is less than the reference amount, the carrying speed of microcapsule paper is decreased so as to obtain the prescribed exposure amount, and the heating temperature is lowered so that the heating amount of a developing paper 17 can be fixed in responce to this decrease in the carrying speed. Thus, even when the light amount of the light source lamp is secularly decreased and the exposure amount is decreased, the prescribed exposure amount can be obtained, and the picture can be maintained at a fixed degree of fixing and gloss.
